About Keflex
Keflex is considered a cephalosporin antibiotic, which functions by stopping the growth of bacteria. Like any cephalosporin antibiotic, this medication can only be used to treat bacterial infections. It is ineffective against cold and flu viruses because they are viral infections.
Some conditions that Keflex is known to treat include infections caused by bacteria, including ear, skin, urinary tract, and upper respiratory infections. Keflex is available only by prescription. It is available in a generic formulation as well as under different brand names, including Bio-Cef and Panixine DisperDose.
Keflex may be prescribed in a capsule: 250 mg, 500 mg, and 750 mg. It’s always important to follow the specific instructions on your prescription, as they can vary based on the formulation and dosage that you are prescribed.
If you are prescribed Keflex, be sure to complete the full course unless your doctor specifically tells you to stop.
If you don’t complete your prescription, the cephalosporin antibiotic may not fully treat your bacterial infection.
